How do you factor 4x^3 -28^2-x+7

-x+4

Step-by-step explanation:

given that

(x^3-4x^2+7x-28)÷(x^2+7)

or

first (x^2+7) × -x = -x^3-7x

so (x^3-4x^2+7x-28) + (-x^3-7x) = -4x^2-28

agian (x^2+7)×(4) = 4x^2+28

so, (-4x^2-28) + (4x^2+28) = 0

i think the answer is d im not sure

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
